SECURIG lMEANS FOR CORRUGATED BUILDING SHEETS.

Application fried August 1o, 1927'. seria1 Nt. auen.

My invention relates to means for securing sheets to a building, and particularly relates to the securing of corrugated sheet material.

vThe general object of my invention is to effect a more secure, stronger and more rigid attachment of the sheets as` well as to provide a fastening means easy of application, light in weight and of lovtr cost as Compared with the forms 'of fastening means now generally used.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the in- Ventron.

Figure 1 is a transverse sectional viewof a sheet fastening means embodying my inv`ention, showing the same in use in association with sheet material to be secured by the fastening means and a portion of the purlin to which the fastening meansV isheld.

Figure 2 is a section on the line 2-'2 of Figure 1.

Figure 3 is a horizontal section on the line 3-,3 of Figure 1.y n

Figure 4 is a transverse vertical section onthe line 4-4 of Figure 1. v Figure 5 is a plan view of the fastening clip before being bent into channel foim.

Figure 6 is an edge View of Vsaid blank.

In carrying out my invention in practice in accordance with the illustrated example, the sheets 10 are secured as follows. A- channel shaped clip 11 or clip generally of U-form, is provide/d to present sides 12 vspaced apart. Said clip 11 is formed kfrom the blank shown in Figures 5 and 6, andis formed at one edge withV openings `13 extending from. said edge, in which openings is entered the flange 14 of a purlin 15.

A bolt 16 passes through a hole in the sheets 10 and through a hole 17 in the top of the clip 11, and is provided with a nut 18. The sides 12 of the clip 11 areformed rwith holes 19 and the material of the clip at the holes and resulting from the forming of the l0 latter, is bent laterally inward in the'form of iianges 20, between which flanges the nut 18 is held as clearly shown in Figure 4.

A clip 21 formed of wire or length of rod presents two top arms 21 spaced apart and said arms are bent downwardly at right angles .to form a depending loop 22 which eX- tends above the `shanl of a headedy stud 23 rlgid on the purlin 15. The ends of the arms 21opp`osite the central depending loop 22 are returned in the form ofhoOks 24, shown best in Figure 3, and these hooks 24 are engaged in notches 25 in that edge of the clip 1-1 opposite the 'edge in which the openings 13i are formed. f

lBy providing the spaced sidesy or flanges on the yclipl 11, a two line seating of the vclip on the top 14 of the pn'rlin 15 results, due to the fact that said sides are spread apart, and this affords a more rigid and solid seating and gives,y greater vsecurity of attachment of the clip than yis possible with clips hayi'ng seating and clampingrneans `at ne pointer along one line only. lTheloiwer walls of the openings 13 seat also snugly against the under sideof the purlin flange 14, and an 75 additional tightness of clamping can be effected' by cold spreading the lower edges of the sides 12, as indicated at 112 inv Figtire 4. UThat is to say, the lower portions 'of the flangsare spread apart beyond the general planesA of the sides, and therefore the lowei` edges of the sides are further apart than the remainder 'of said sides, the result bei-ng that the clip is fixed securely against lateral displacement on the purlin. Further, the channel or U-sha'peof thev clip provides a broad support beneath the corrugated sheets more than do the Hat disconnected bandsv or wires heretofore employed, as the top of the clip is given rigidity by the solid two line or two point seating or clampingof the clips, so that the position of the clip on the purlin or girt 14, 15, is in no way dependent, as is the caseY with common forms of fastening now in use, uponth'e tightness of the connection ofthe 95 attached sheet to the clips, but is independent of such tightness, Ywith the result that no unduestrain need be nutupon the sheets in order to tightly secure them to the 'clips' for fixed attachment on the piirlin or other b'uild- 100 ing member.A

In association with the bolt, a lead washer 26 having a cap 27 thereon, is provided be,- neath the head of the bolt 16, also a seating washer 28 of suitable yielding material is 105 provided on the bolt at the under side of the corrugated sheet 10.

To further increase the tight engagement of the clip 11 with the flange 14 of the purl in, chisel indentations 29 are produced in the 110 under side of said flange 14 and the opposed terminal points 30 of the sides 12 are driven into tight clinching contact with the flange 14 at said indentations 29 (see Figure l).

An additional hole S1 in transverse alignment with the bolt hole 17 in the clip l1 enables a supplementary clamp to be employed.

vWith my described assemblage there is less need and less danger of breaking the sheet material l0 or putting on the sheets too great tightening strains, which Very frequently causes said sheets to later break or crack under a heavy wind pressure', such danger from too much tightening' being thus eliminated by my invention and which danger exists due to the use of clip forms or similar means now 'in use for attachment of sheets of heavy material of corrugated form to steel frames of supporting members in walls or roofs.4

rThe material which the invention is especially adapted to secure is asbestos-cement corrugated sheets, the imperfect fastening of which by the present means is well known.

It is to be noted that the bolt 16 is inserted in the outer side of the sheets downwardly or inwardly, according to whether it is a roof or a wall that is being covered. The head end of the bolt is exposed to the weather. Furthermore, it is to be observed that the nut 18 is in direct engagement with the flanges 20 of the sides 'l2 of the clip ll, andY remote from the cover sheet l0; this serves to hold the screw in lixed position relatively to the bolt hole, even before the sheet l() is fastened tightly to the clip, thus making the fixing and support of the sheet in its proper position independent of the tightness of the bolt head against the sheet. The fixed engagement of the nut 18 against the clip ll when the bolt is turned up tightly avoids any concentrated load, such as a stepping on the bolt head, from harming the lead washer 26 or the resilient washer 28, the pressure being all taken up by the nut and clip and through the clip directly to the purlin or other frame member.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, l do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be coirsideralily varied without departure from the spirit of the invention as defined in the appended claims.
